class openff.qcsubmit.workflow_components.PfizerFragmenter(*, type='PfizerFragmenter', target_torsion_smarts=None)[source]

The openff.fragmenter implementation of the Pfizer fragmenation method as described here (doi: 10.1021/acs.jcim.9b00373)

Parameters
Return type

None

__init__(**data)

Create a new model by parsing and validating input data from keyword arguments.

Raises ValidationError if the input data cannot be parsed to form a valid model.

Parameters

data (Any) –

Return type

None

Methods

__init__(**data)

Create a new model by parsing and validating input data from keyword arguments.

apply(molecules, toolkit_registry[, ...])

This is the main feature of the workflow component which should accept a molecule, perform the component action and then return any resulting molecules.

construct([_fields_set])

Creates a new model setting __dict__ and __fields_set__ from trusted or pre-validated data.

copy(*[, include, exclude, update, deep])

Duplicate a model, optionally choose which fields to include, exclude and change.

description()

Returns a friendly description of the workflow component.

dict(*[, include, exclude, by_alias, ...])

Generate a dictionary representation of the model, optionally specifying which fields to include or exclude.

fail_reason()

Returns a friendly description of why a molecule would fail to pass the component.

from_orm(obj)

info()

Returns a dictionary of the friendly descriptions of the class.

is_available()

Check if fragmenter can be imported.

json(*[, include, exclude, by_alias, ...])

Generate a JSON representation of the model, include and exclude arguments as per dict().

parse_file(path, *[, content_type, ...])

parse_obj(obj)

parse_raw(b, *[, content_type, encoding, ...])

properties()

Returns the runtime properties of the component such as parallel safe.

provenance(toolkit_registry)

Collect the toolkit information and add the fragmenter version information.

schema([by_alias, ref_template])

schema_json(*[, by_alias, ref_template])

update_forward_refs(**localns)

Try to update ForwardRefs on fields based on this Model, globalns and localns.

validate(value)

Attributes

type

classmethod description()[source]

Returns a friendly description of the workflow component.

Return type

str

apply(molecules, toolkit_registry, processors=None, verbose=True)

This is the main feature of the workflow component which should accept a molecule, perform the component action and then return any resulting molecules.

Parameters
Returns

A component result class which handles collecting together molecules that pass and fail the component

openff.qcsubmit.workflow_components.utils.ComponentResult

classmethod fail_reason()

Returns a friendly description of why a molecule would fail to pass the component.

Return type

str

classmethod info()

Returns a dictionary of the friendly descriptions of the class.

Return type

Dict[str, str]

classmethod is_available()

Check if fragmenter can be imported.

Return type

bool

classmethod properties()

Returns the runtime properties of the component such as parallel safe.

Return type

openff.qcsubmit.common_structures.ComponentProperties

provenance(toolkit_registry)

Collect the toolkit information and add the fragmenter version information.

Parameters
